Abstract
A mobile device may transition between Extended Service Set (“ESS”) networks while maintaining the same internet protocol (“IP”) address while transitioning. The transition may occur seamlessly, such that a consumer never loses the network connection despite transitioning between networks. The mobile device may receive an IP address from a pool of addresses, such that the mobile device can keep that IP address as it is transitions between networks that each have access to the pool. The assignment of the IP address to the mobile device is from the pool of IP addresses rather than from the AP.
Claims20
A method performed by a mobile device, comprising:
- requesting a connection with a first Extended Service Set (ESS) wireless network;
- receiving an internet protocol (IP) address from the first ESS wireless network after requesting the connection with the first ESS wireless network, wherein the IP address is received from a server with IP addresses that are available through both the first ESS wireless network and a second ESS wireless network;
- receiving, from the first ESS wireless network using Access Network Query Protocol (ANQP) prior to associating with the first ESS wireless network, an indication of support for transitioning to different ESS wireless networks while maintaining the IP address;
- and
- transitioning from the first ESS wireless network to the second ESS wireless network while maintaining the IP address.
A system for transitioning between Extended Service Set (ESS) wireless networks, wherein the system comprises:
- a mobile device configured to:
- transmit a request for a connection with a first ESS wireless network;
- receive an internet protocol (IP) address from the first ESS wireless network subsequent to transmission of the request for the connection with the first ESS wireless network, wherein the IP address is received from a server with IP addresses that are available through both the first ESS wireless network and a second ESS wireless network;
- receive, from the first ESS wireless network using Access Network Query Protocol (ANQP) prior to associating with the first ESS wireless network, an indication of support for transitioning to different ESS wireless networks while maintaining the IP address;
- and
- transition from the first ESS wireless network to the second ESS wireless network while maintaining the IP address.
A non-transitory computer-readable medium configured to store a computer program product comprising computer executable instructions that, when executed by a processor of a mobile device, cause the processor to be configured to:
- transmit a request for a connection with a first Extended Service Set (ESS) wireless network;
- receive an internet protocol (IP) address from the first ESS wireless network subsequent to transmission of the request for the connection with the first ESS wireless network, wherein the IP address is received from a server with IP addresses that are available through both the first ESS wireless network and a second ESS wireless network;
- receive, from the first ESS wireless network using Access Network Query Protocol (ANQP) prior to associating with the first ESS wireless network, an indication of support for transitioning to different ESS wireless networks while maintaining the IP address;
- and
- transition from the first ESS wireless network to the second ESS wireless network while maintaining the IP address.
